CROSS-REFERENCE(S) TO RELATED APPLICATIONS

The present application claims priority to Chinese Patent Application No. 201621118083.5 filed on Oct. 13, 2016, and priority to Chinese Patent Application No. 201621407062.5 filed on Dec. 20, 2016, the entire contents of which are incorporated herein for all purposes by this reference.

FIELD OF THE INVENTION

The present disclosure relates to tent frames, and, more particularly, the present disclosure relates to eave structures and tent frames having the same.

BACKGROUND

In general, tents are available in a variety of sizes and structures. Small to medium sized tents are typically utilized for mobility and camping, while larger pavilion sized tents provide large shaded regions.

Conventional tents comprise supporting poles, an upper frame supported by the supporting poles and a tent cloth covering the upper frame. The given shaded region of the tent is proportional to an area formed by the tent cloth. Increasing the shaded region requires an enlargement of the tent frame, including increasing a length of the frame poles. The increased size of the frame poles requires auxiliary support to ensure the stability of the tent, thus a weight of the tent increases.

Another means to provide a larger shaded region is to include an eave structure with the tent frame. FIG. 1 and FIG. 2 illustrate an existing tent including eave structure 2 a disposed on each supporting pole 1 a. Eave structure 2 a includes primary eave pole 21 a and support eave pole 22 a. A first end portion of primary eave pole 21 a is pivotally connected to a fixed connector at an upper end portion of supporting pole 1 a, and a second end portion is connected to the tent cloth. A first end portion of support eave pole 22 a is pivotally connected to sliding connector 23 a which is slidably connected with supporting pole 1 a. A second end portion of support eave pole 22 a is pivotally connected to primary eave pole 21 a. Eave structure 2 a and an upper frame may be folded and unfolded together.

The above configured tent requires a stopper to be disposed to the eave structure, limiting the movement of the sliding connector. Further, the tent cloth is likely to sag and is easily depressed between the eave structures as a distance between adjacent eave structures is large. As such, the tent is unattractive and has a tendency to accumulate rain or snow on the tent cloth.

Thus, prior to the present disclosure there existed a need for eave structures and tent frames that address the abovementioned issues.

The information disclosed in this Background of the Invention section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

These terms are only used to distinguish one element from another. For example, a first subject could be termed a second subject, and, similarly, a second subject could be termed a first subject, without departing from the scope of the present disclosure. The first subject and the second subject are both subjects, but they are not the same subject. Furthermore, the terms “subject” and “user” are used interchangeably herein.

In the interest of clarity, not all of the routine features of the implementations described herein are shown and described. It will, of course, be appreciated that in the development of any such actual implementation, numerous implementation-specific decisions must be made in order to achieve the developer's specific goals, such as compliance with application- and business-related constraints, and that these specific goals will vary from one implementation to another and from one developer to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking of engineering for those of ordinary skill in the art having the benefit of this disclosure.

Various aspects of the present disclosure are directed to providing eave structures and tent frames having such eave structures. Generally, a tent frame of the present invention includes a plurality of supporting poles, a plurality of side pole units, and an upper frame connected to the plurality of supporting poles or the plurality of side pole units or both. The tent frame can be a plurality of sizes and shapes, and can include any number of supporting poles including three, four, five, or more supporting poles. The tent frame of the present invention also includes a plurality of eave structures, a number of which may be varied depending on a designer's preference. For instance, the tent frame may include two eave structures, three eave structures, or a number corresponding to the number of supporting poles.

An eave structure typically comprises a first primary eave pole and a second primary eave pole pivotally connected with a fixed connector at a supporting pole. The eave structure also comprises a first support eave pole and a second support eave pole connected with one or more sliding connectors at the supporting pole and with the corresponding first and second primary eave poles. When the tent frame is unfolded, the eave poles extend beyond the upper frame and/or supporting pole. Such an eave structure, along with the upper frame, can be used to support a tent cloth including a canopy. As the eave poles extend beyond the tent frame, the shaded region increases and further protects occupants from rain or snow.

In some embodiments, the first and second support eave poles are connected with one sliding connector at the supporting pole. In some embodiments, the first and second support eave poles are connected to two different sliding connectors at the supporting pole.

Referring to FIG. 3 to FIG. 8, there is depicted a tent frame according to an exemplary embodiment of the present invention. As shown, the tent frame includes a plurality of supporting poles 1 with a plurality of fixed connectors 11 and a plurality of second connectors 12 disposed on the supporting poles and configured to connect the supporting poles to various elements of the tent frame. In some embodiments, each fixed connector is fixedly coupled with a supporting pole at an upper end portion (e.g. the top) of the supporting pole. Each second connector is slidably coupled with a supporting pole and movable along the supporting pole below the first connector. Further, a plurality of side pole units 21 each couple two adjacent supporting poles though one or more of the fixed and second connectors of the two adjacent supporting poles.

The tent frame also includes an upper frame, such as upper frame 2, coupled with the plurality of supporting poles. Upper frame 2 is disposed above and supported by the plurality of supporting poles when the tent frame is unfolded. In some embodiments, upper frame 2 includes hub 22, and a plurality of upper pole units. In the illustrated embodiment, each upper pole unit comprises upper pole 23 and oblique pole 24. In some embodiments, each upper pole 23 comprises a first upper pole and a second upper pole directly or indirectly coupled with each other. Each of the first upper pole, second upper pole, and oblique pole has a first end portion and a second end portion. The first end portion of each first upper pole 23 is pivotally connected to the hub. Each second upper pole 23 is pivotally connected with the corresponding first upper pole, directly or indirectly. The second end portion of each second upper pole 23 is pivotally connected with the corresponding fixed connector. The first end portion of each oblique pole 24 is pivotally connected with the corresponding second upper pole. The second end portion of each oblique pole 24 is pivotally connected with the corresponding second connector. Further, each side pole unit 21 is coupled with two adjacent supporting poles 1 by fixed connector 11 and second connector 12 at the two adjacent supporting poles.

In some embodiments, each side pole unit in the plurality of side pole units comprises one or more side pole pairs connected with each other, wherein each side pole pair comprises first and second side poles crossly and pivotally connected with each other, and each of the first and second side poles adjacent a supporting pole has an end portion pivotally connected with the fixed or second connector at the supporting pole.

In some embodiments, the upper frame comprises alternative, additional, or optional components. For instance, referring to FIG. 9, in some embodiments, upper frame 2 comprises hub 22, sliding hub 27, central pole 25, and a plurality of upper pole units. Hub 22 is fixedly coupled with the central pole at a lower end of the central pole, and in some cases, is termed as a fixed hub. Sliding hub 27 is slidably coupled with the central pole and movable along the central pole above the hub. Each upper pole unit is disposed between the central pole and a side pole unit in a plurality of side pole units. It should be noted that the term “central pole” as used herein can be, but does not necessarily have to be, at a center of the tent frame.

In some embodiments, each upper pole unit comprises one or more upper pole pairs connected with each other. Each upper pole pair comprises first and second upper poles crossly and pivotally connected with each other. Each of the first and second upper poles adjacent the central pole has an end portion pivotally connected with the fixed or sliding hub at the central pole. Further, each of the first and second upper poles adjacent the side pole unit has an end portion pivotally connected with the first or second side pole of a corresponding side pole pair of the side pole unit. By way of example, FIG. 9 illustrates each upper pole unit comprising one pair of upper poles 23, disposed between central pole 25 and corresponding side pole 21, in a pivotable crossing, scissor, or X fashion.

The tent frame further includes two or more eave structures 3, and connectors to couple the eave poles with the upper frame and the supporting poles, or various elements disposed on the supporting poles. In some embodiments, an eave structure includes a plurality of eave poles. In some embodiments, an eave structure includes a plurality of eave poles and a mechanism (e.g., a connector or a link) coupling the eave poles with the upper frame and/or a supporting pole.

In various embodiments, each eave structure comprises a first primary eave pole, a second primary eave pole, and corresponding first and second support eave poles. The primary eave poles have first end portions pivotally coupled to a fixed connector, and the support eave poles have first end portions pivotally coupled with one or more sliding connectors. The second end portion of each primary eave pole and the corresponding support eave pole are coupled to each other. When the tent frame is unfolded, the primary eave poles extend outwardly and upwardly with respect to the supporting pole, and form a first angle in-between. In an exemplary embodiment of the present invention, the first angle is approximately 90°.

Referring to FIG. 3 to FIG. 14, in some embodiments, each eave structure 3 comprises first primary eave pole 31A, second primary eave pole 31B, first support eave pole 32A, and second support eave pole 32B. The first end portions of primary eave poles 31 are pivotally coupled to fixed connector 11, and the second end portions of primary eave poles 31 are pivotally coupled to the second end portions of corresponding support eave poles 32. First end portions of support eave poles 32 are pivotally coupled to sliding connector 12, which is configured to slidably move along supporting pole 1. In some embodiments, the second end portion of each support eave pole is pivotally coupled to an intermediate portion of the corresponding primary eave pole.

Referring to FIG. 15 to FIG. 22, in some embodiments, each eave structure 3 comprises first primary eave pole 31A, second primary eave pole 31B, first support eave pole 32A, and second support eave pole 32B. The first end portions of primary eave poles 31A and 31B are pivotally coupled to fixed connector 11, and the second end portions of primary eave poles 31A and 31B are pivotally coupled to the corresponding second end portions of support eave poles 32A and 32B. The first end portion of first support eave pole 32A is pivotally coupled to second connector 12, and the first end portion of second support eave pole 32B is pivotally connected to third connector 13.

As described above, since second connectors 12 are mutually connected through side pole units 21, the eave poles coupled thereto form linked eave structures 3A comprising first eave poles. Unlinked, or separate, eave structures 3B, comprising second eave poles, are thus formed through standalone third connectors 13.

In the present case, the plurality of first primary eave poles and the plurality of first support eave poles are linked to each other through the mutual connection of the second connectors and the side pole units. The linkage folds and unfolds as a whole. On the other hand, the plurality of second primary eave poles and the plurality of second support eave poles are unlinked and can be individually deployed or unfolded as there are no mutual connections.

In some embodiments, the tent frame further comprises a cross pole interposing eave poles of adjacent supporting poles. The cross pole is coupled, for instance, by inserting an end of the cross pole into an insertion hole formed at the second end portion of each primary eave pole. In some embodiments, the cross pole comprises a plurality of segments such as a first segment and a second segment pivotally connected to each other.

Referring to FIG. 17 and FIG. 18, in some embodiments, insertion hole 311 is formed at the second end portion of each primary eave pole 31, and cross pole 4 is removably inserted into the insertion holes of corresponding primary eave poles 31 of adjacent supporting poles 1. Cross pole 4 is configured to further extend a tent cloth and prevent sagging thereon.

It should be noted that a tent frame of the present invention can include a various number of eave structures, depending on the designer's preference. It should also be noted that tent frame of the present invention can include different types of eave structures in the same tent frame. For instance, in an embodiment where only one side of the tent needs shade, the tent frame can include two eave structures, with each eave structure connected with one of two adjacent supporting poles. In an embodiment where two sides of the tent need shade, the tent frame can include three eave structures, with each eave structure connected with one of three adjacent supporting poles. In a further embodiment where all sides of the tent need shade, the tent frame can include the same number of eave structures as the supporting poles, with each eave structure connected with one of the supporting poles.

The eave structure of the present invention can be folded and unfolded along with the other members of the tent frame, except the eave structure 3B illustrated in FIG. 15 to FIG. 22 which can be independently folded and unfolded at any time when desired. For instance, referring to FIG. 3, in some embodiments, when unfolding the tent frame, the plurality of supporting poles 1 are pulled outwardly (e.g., away from each other). First and second upper poles 23 are unfolded to form a substantially straight line. Second connector 12 slides upwardly along supporting pole 1, pushing the eave poles 31 and 32 outwardly beyond the upper frame and/or supporting poles, extending side poles 21 laterally. In some embodiments, such as that illustrated in FIG. 20, second connector 12 only deploys eave poles 3A, and third connector 13 must slide upwardly along supporting pole 1 to push eave poles 3B outwardly beyond the upper frame and/or supporting poles.

Referring to FIG. 6, FIG. 7, and FIG. 8, when folding the tent frame, second connector 12 slides downwardly along supporting pole 1, pulling oblique pole 24 and side poles 21 downwardly. In turn, the oblique pole pulls downwardly upper poles 23, and accordingly primary and support eave poles 31 and 32 retract to be parallel to the supporting pole. Side pole units 21 constrict according to the downward motion of second connector 12.

Referring to FIG. 12 to FIG. 14 and FIG. 19 to FIG. 22, in some embodiments, when folding the tent frame, second connectors 12 and, when applicable third connectors 13, slide downwardly along supporting pole 1, wherein each of side poles 21, upper poles 23, and eave poles 31 and 32 retract to be parallel with the supporting poles. As illustrated in FIG. 8, FIG. 14, and FIG. 22, the folded tent frame, or tent, is compact with all poles folded towards each other.

Referring to FIG. 23 to FIG. 25, the tent frame can be used to support cloth 5. As shown, depending on the number, location, and deployment of the eave structures the tent can assume a variety of shapes and structures according to the designer's or a user's preference.

As disclosed herein, when the tent frame is unfolded, the second end portion of eave poles 31 and 32 extend outwardly beyond the upper frame and the supporting pole. Further, a distance between adjacent eave poles is small, and thus sagging between eave poles can be prevented. Additionally, the eave structures of the present invention can be used to extend the tent cloth, including a canopy, beyond the sides of the tent. As a result, the eave structures help to provide a larger shaded region on sunny days. The eave structures of the present invention also help to smooth the tent canopy and prevent sagging, thus reducing a risk of accumulating water or snow. Further, when the tent frame of the present invention is folded, the structure is compact, thus increasing the mobility and storage capacity of the tent.
